Abstract: An apparatus with embedded water detection and heater includes a substrate including a number of conductive traces and a lid including multiple electrodes. Each electrode is coupled to at least one of the conductive traces through vias. A sensor is placed inside a cavity of the lid and is electrically coupled to one or more conductive traces of the substrate. A gel at least partially fills the lid and covers the sensor. The presence of water on the apparatus is detected by measuring a dielectric permittivity between at least two of the plurality of electrodes, and the electrodes can generate heat to eliminate the water.

Abstract: Aspects of the subject technology relate to an apparatus having a housing including a port exposed to an environment. A pressure sensor is disposed within the housing to measure a pressure of the environment. A medium partially fills a sensor cavity or is coated over the pressure sensor, and a cap including multiple openings is disposed over the pressure sensor. The openings of the cap are arranged to be offset from the port.

Abstract: According to some aspects of the subject technology, an apparatus includes a first electrode, a second electrode and a dielectric membrane disposed between the first electrode and the second electrode. The first electrode and the second electrode include a number of pores within a region of an input port of the apparatus. The first electrode, the second electrode and the dielectric membrane form a capacitor that is configured to enable detection of occlusion of the input port by water.
